Common symptoms
- Runs but the water stays cool: can be low flow, a bypass issue, a sensor, or a heat pump that is no longer moving heat.
- Short cycling: the unit starts and stops, often from flow, a dirty filter, or a control problem.
- Error codes or lockouts: write them down; they help the technician start in the right place.
- Ice on a heat pump: some frost in cool, damp air can be normal, but heavy ice or repeated icing needs a look.
- Gas heater will not ignite or stay lit: ignition, gas supply, venting or a safety switch may be involved.
If the unit is already old, ask for a repair price next to a replacement price. See how long pool heaters last.
What to have ready
The brand and model if you can read them, the approximate age, any error codes, and whether the pool pump and filter have been running normally all help. Mention if you recently changed a pump, added a salt system, or had low water flow. Photos of the data plate and the pad are useful in the notes field.
